8KRA2+ Booting from USB-Stick Problems

[Fallacy]

hi,

I´ve some Problem with my 8KRA2+ and booting from USB-Stick. The USB-Stick is defintily bootable. It´s a Xstor USB 2.0 Stick. Under Windows it works fine with this board. And i can boot from the USB-Stick with my Father´s Board (Asrock K7S8XE) and with my Sister´s Mainboard (Epox 8RDA+). But i don´t get it working with my Epox 8KRA2+.
When i go into the Bios, the USB-Stick is correctly identified as "USB-HDD0: USB Mass Storage Drive" in the category "Hard Disk Boot Priority". I´ve tried the following Settings:
-> Hard Disk Boot Priority
1. USB-HDD0: USB Mass Storage Drive
2. Ch0.M.: Maxtor 6L080J4
3. Bootable Add-in Cards

First Boot Device -> USB HDD (also tried USB-ZIP and USB-FDD)
Second Boot Device -> Disabled
Second Boot Device -> Disabled

I also tried:
1. USB-HDD0: USB Mass Storage Drive
2. Ch0.M.: Maxtor 6L080J4
3. Bootable Add-in Cards

First Boot Device: Harddisk
Second Boot Device: USB-ZIP
Third Boot Device: Disabled

But every time i boot, the following message appears:
Verifying DMI Pool Data
Missing Operating System

I´ve tried different Bios Versions. kra24130 and at the moment i´m using kra24139.
I hope somebody here could help me.

Sorry for my bad english

I dunno about your particular problem, but the world will be a very happy place for me when all USB sticks will be bootable in all motherboards. DIE FLOPPY DIE!

How did you format your USB stick?

The 8Kra2+ is generally unstable with USB devices on boot, shutdown etc. I know if i keep my usb pen OR 6 in 1 card reader in the system will be so unstable. Waiting for a new bios but i dont think that will ever happen
